From daead48672e56af966911abc4efe1e54573c02cc Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Fri, 1 Aug 2025 22:53:54 +0300 Subject: implemented the ^W command for refreshing the screen in loops, for sleeping and also the CTRL+L immediate editing command * ^W can be added to loops in order to view progress in interactive mode. It also sleeps for a given number of milliseconds (10ms by default). * In batch mode it is therefore the sleep command. * Since CTRL+W is an immediate editing command, you will usually type it Caret+W. ASCII 23 however will also be accepted. * While ^W only updates the screen, you can force a complete redraw by pressing CTRL+L. This is what most terminal applications use for redrawing. It will make it harder to insert ASCII 12, but this is seldom necessary since it is a form feed. ^L (ASCII 12 and the upcaret variant ) is still a whitespace character and therefore treated as a NOP. * DEC TECO had CTRL+W as the refresh immediate editing command. Video TECO uses as a regular command for refreshign in loops. I'd rather keep ET reserved as a potential terminal configuration command as in DEC TECO, though. --- tests/testsuite.at | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tests/testsuite.at') diff --git a/tests/testsuite.at b/tests/testsuite.at index 78e6f48..7fecc45 100644 --- a/tests/testsuite.at +++ b/tests/testsuite.at @@ -357,7 +357,7 @@ AT_CLEANUP AT_SETUP([Timestamps]) # TODO: Test the date (^B) and time (^H and :^H) variants as well. -TE_CHECK([[::^HUa ::^H-Qa"<(0/0)']], 0, ignore, ignore) +TE_CHECK([[::^HUt 100^W (::^H-Qt)-100"<(0/0)']], 0, ignore, ignore) AT_CLEANUP AT_SETUP([Program version]) -- cgit v1.2.3
